Patented April '7, 1908.

Application filed June 29, 190']. Serial No. 333.38%.

To all whom it may concern:

Be it known that l, EZRA S. BUCKNAM, e citizen of the United States, and s. resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful lin movements in Cer-lVindows, of which the following is a specification. I

The object of my invention is to produce a sash for car windows having a very simple, eliicient and inexpensive means for engaging a projection on the car stanchion so that the sash may be held in any of several positions.

[In the drawings forming part of this application: Figure ],-is a perspective view 0 a, portion of a, cor showing my improved lg. 22 is a cross section through a portion of the side of s cor showing the window closed. Fig. 3 is 9. section on the line 3-3 of Fig 2. Fig. 4 is a; perspective view of a portion of e cor store chion showing the engaging stop,snd,Fig. 5 is an elevation of the edge of the sash.

The car may be of any construction and therefor it is only necessary to show such certs es are associated with my invention. lhere are side posts or stanchioiis 1 to which is secured the outer sheathing, 2, and a. letter board 3, in the usual way. The stsnohias are provided on their sides with sesh grooves 4, running vertically and they are preferably increased in width from the letter board to the belt rail 5, with a. shoulder 6 formed near the letter to form an abutment for the sash when in its closed position.

Within the groove 4 is a stop or projection 7 on which the sash engages to retain it in. its several raised ositions and it is preieo ably near the outer imit of the groove 4 and provided. with a. slanting under side 8. I

The sash 9, is provided on its side edges with recesses. 1.0 which reject inwardly and reerwcrdly a. ortion 0' the thickness of the sash but not" t is entire thickness of the sash. These recesses are provided with an inclined lower surface 11 corresponding to the inclined surface 8 of the projection. On the interior face of the sash I provide s rings 12 which are arranged above the 'mid e oi the sash.

When the sash is arranged in its proper place hetween'tlie stenchions, it is adapted to rest in its normal or closed position on the shoulder 5, when the projection or stop I will lie in iippermost recess 10.

When it desired to open the car window, the sash 9 is raised and if the o )orstor does not drew the sash inwardly to al ow the sash to pass the stop, the slanting surfaces 8 end 11 will cause u. trudging action which will overcome the act-ion oi' the springs 12 and force the lmvorportion of the sash inwardly enough to allow the sash to be raised until a lower one of the recesses 10 engages the stop 7, when the sash is released and'the springs 12 keep it from becoming disengaged. The grooves 4 es was explained sulliciently wide stthe lower portion to allow the sash to he moved inwardly when passing the sto 7.

15y making the car as here shown, the sash is made adjustable in height very easily, and no operating ports are in sight, whioh odds to its appearance. Besides this, the recesses 10 do not prevent the connection between the sash and stenchions being weathertight.

Any desired number of recesses 10 may he used in order to provide for the sash being held in various positions;

Having described my invention, Wh at I claim is:

l. A railway car provided with stanchions having it groove formed between an inner and outer sash guiding strip, a sash movable in said grooves thefeces of which engage thesaid guiding strips, said sash being provided with a recess extending inwardly from that part of the face of the ssshwhich engages the guide strip, for a portion of the thickness of thesesh, a projection in the'scsh groove adapted to engage in the scshrecess and a spring adopted to iorce thesnsh toward the said proj ection, the" sash grooves hein wide enough-to allow the sash to be moved rec of the projection.

2. A railway car provided WllZ-ll stsnchions having a groove formed between inner and outer sesh guiding strips, :1 projection on the outer guide strip extending inwardly into the groove, 11 sash movable in the grooves and 10 provided with recesses in its outer face to re ceive the" said EIOJGCUOI! and s s rin adapt ed to force t e sash outward y, t e sash grooves being sufiiciently wide to allow the sash to be moved inwardly and. free of the said projection.
